Muttenz
municipality in the canton of Basel-Landschaft in Switzerland

Muttenz is a municipality with a population of about 17,000 in the canton of Basel-Country in Switzerland. It is in the district of Arlesheim, next to the city of Basel.
History
Under the Roman Empire a hamlet called Montetum existed, which the Alamanni invaders referred to as Mittenza since the 3rd century CE. At the beginning of the 9th century CE the settlement came into the possession of the bishopric of Strasbourg. In the following centuries various noble families were invested with the fief.
Muttenz is first mentioned around 1225–26 as Muttence. In 1277 it was mentioned as Muttenza.
In 1306 the village became the property of the Münch of Münchenstein, who fortified the village church of St. Arbogast with a rampart at the beginning of the 15th century, after their fortresses on the nearby Wartenberg were partially destroyed in the devastating Basel earthquake of 1356. Having fallen on hard times the Münch sold the village and the Wartenberg to the city of Basel in 1517. Following the Protestant Reformation in Basel by Johannes Oecolampadius the church of Muttenz was reformed in 1529.
